Magnetic and Dielectric Amplifiers
(MIT Digital Computer Laboratory, 1952-08-28)This paper was prepared at the request of Professor Arthur R. von Hippel for presentation at a summer symposium on the Theory and Applications of Dielectric Materials, September 3-12, 1952, at the Massachusetts Institute ... -
Magnetic Core Activity
(MIT Digital Computer Laboratory, 1952-01-15)The 16 x 16 metallic array has been operated successfully. Only partial operation of the 16 x 16 ceramic-core switch-driven array has been accomplished. Some progress has also been made with pulse transformer investigations, ... -
Magnetic Core Matrix Switch Adder
(MIT Digital Computer Laboratory, 1953-03-09)The principle of operation of the three input-two output matrix adders is based upon the saturable transformer characteristics of the magnetic cores. The control and driving windings are matrix connected. This presents a ... -
A Magnetic Core Test Storage
(MIT Digital Computer Laboratory, 1953-06-15)The toggle-switch test storage units in WWI and MTC use large numbers of crystal diodes and vacuum tubes. A much simpler unit might be possible using a modified magnetic matrix switch which will both select the words and ... -
Magnetic Devices Inc., a Trip Report
(Lincoln Laboratory - Division 6, 1953-12-15)Magnetic Devices, Inc. of Fredrick, Maryland was visited to determine whether rotary relays showed enough promise for either marginal checking or power distribution use to warrant further investigation. It was our conclusion ... -
Magnetic Material Charges
(MIT Digital Computer Laboratory, 1951-12-28)Memorandum by Digital Computer Laboratory staff on changes to accounting for magnetic materials charges. -
Magnetic Materials for High-Speed Pulse Circuits
(MIT Digital Computer Laboratory, 1953-02-27)Magnetic materials are attractive for digital computer systems and other large pulse-circuit systems because they promise to be stable and trouble free. Ultra-thin molybdenum-permalloy cores and ferrite cores possessing ... -
A Magnetic Matrix Switch and its Incorporation into a Coincident-Current Memory (Abstract of R-211, an M.S. Thesis)
(MIT Digital Computer Laboratory, 1952-11-20)This memorandum contains the abstract of Report R-211, a Master's Thesis, by Kenneth H. Olsen. -
A Magnetic Matrix Switch and its Incorporation into Coincident-Current Memory
(MIT Digital Computer Laboratory, 1952-06-06)The random-access memory is an important element of a high-speed digital computer. This memory must be capable of operating at high speeds with long-time reliability, and should be compact and of low cost. The coincident-current ... -
Magnetic Memory Plane Insulation Resistance Tests
(Lincoln Laboratory - Division 6, 1953-09-02)Insulation resistance measurements were made on two 16 x 16 and seven 32 x 32 magnetic memory planes, in order to determine the extent of abrasion caused by threading the wire through ferrite cores. These tests show that ... -
A Magnetic-core Gate and its Application in a Stepping Register
(MIT Digital Computer Laboratory, 1952-10-30)A magnetic-core gate to replace diodes is a necessity if an all-core computer is to be made feasible. A device is described composed of two magnetic cores and a resistance which will operate as a gate between the cores of ... -
Magnetic-Core Matrix Switch Driver (X & Y Plane Driver). PB 18
